Asymptotic Theory of Nearly Free-Molecular Flows
Asymptotic Theory of Nearly Free-Molecular Flows
An asymptotic theory for obtaining nearly free-molecular solutions which are uniformly valid throughout the flow field is proposed in the present study for the linearized Boltzmann equation. The theory is based on an integral-equation formulation of the linearized Boltzmann equation, using an inner-and-outer-expansion procedure. In the inner region the problem …
